2.2寸（14PIN）TFT液晶屏STM32 SPI 控制
屏幕如图所示，共14个IO口（也可能只有13个），控制屏幕的有9个IO口
反面IO口图：
连接通过SPI方式连接：
//默认程序接线说明： #define LCD_CTRL GPIOB //定义TFT数据端口为PB组 #define LCD_LED GPIO_Pin_9 //MCU_PB9 对应接液晶屏(或者模块)TFT --PIN_LED背光正极（背光可以由IO口提供电流，或者外接3.3V电压） #define LCD_CS GPIO_Pin_11 //MCU_PB11 对应接液晶屏(或者模块)TFT --CS #define LCD_SCL GPIO_Pin_13 //MCU_PB13 对应接液晶屏(或者模块)TFT --SCL #define LCD_SDA GPIO_Pin_15 //MCU_PB15 MOSI 对应接液晶屏(或者模块)TFT --SDA #define LCD_SDO GPIO_Pin_14 //MCU_PB14 MISO 对应接液晶屏(或者模块)TFT --SDO #define LCD_RS GPIO_Pin_10 //MCU_PB10 对应接液晶屏(或者模块)TFT --RS/DC #define LCD_RST GPIO_Pin_12 //MCU_PB12 对应接液晶屏(或者模块)TFT --RST
